T0 all whom Ait may concern,.-

Be it'known that I, CHARLES L. MILLER, a

citizen of the United States, residing at Berkeley. in the county ofAlameda and State of California, have invented new and usefullmprovements in Ealing-Presses, of which the following is aspecification.

My invention relates to Vimprovements in baling-presses, and especiallythat class which is designed for baling-hay and like substances.

It consists in the combination and arrangement of parts and in detailsof construction, which will be vmore fully explained by reference tothel accompanying drawings, in which- Figure l is a side elevation of mypress with follower up. Fig. 2 is a. front elevation of same withfollower partly down. Fig. 3 is a rear elev'ation'of same with followerdown.

Fig. 4 is a plan view of eccentric wheel and direction-pulleys. Fig. 5is a viewi-ofreccentric wheel. Flg. 6 1s avlew of incline. Fig. 7 1s ahorlzontal transverse section through baling-chamber, swing movable sideplate.v

Fig. 8 is a top plan view of power end.

My invention is especially designed to be used in that class of presseslhaving a vertical press-box with a means for delivering charges ofmaterial into the upper part of the box, these charges beingsuccessively compressed by means of a follower which is moved downwardby suitable connections, so as to compress the charges successively intothe lower part of the press-box, and-when the bale has been completedand tied it is removed through a door-opening which is 'located belowthe point'at which the material is delivered into the'press. f

fAs shown in the drawings, A is a verticallydisposed press-box ofsufficient height having a follower 2 substantially filling the interiorofthe box transversely, said follower having a bar with stout endsprojecting through vertical slots or channels 3 in the narrow verticalsides of the press, so that, levers 4 may be connected with these endsand power applied to draw the follower down after a charge has beenplaced within the press-box and beneath the follower. rlhe connectionsfor this purpose consist of lever-arms 5, having their inner endsstrongly fulcrumed to the press-box, as shown at 6, and the outer endsconnected with the levers 4, as shown at 7. Chains 8 connect with theends ofthe levers 4, passing downwardly and inwardly therefrom to thebottom of the press, where they pass around guide-pulleys 9, thencearound direction-pulleys 10, and the two chains unite and are suitably`connected with a lrod 11 of suflicient length to extend to the end ofthe horse-power frame 12, where it is connected with achain 13,v andthis chain is adapted to windaround y an eccentric pulley 14;

The rst downward movement of the follower and while the charge to bepressed is loose is comparatively rapid by the direct action of thechains pulling downwardly 'upon the levers 4; but as these leversapproach the sides of the press the movement of the lever 5 in an arcabout their pivot-point 6 will bring them-more nearly into line with thelevers 4,v

and this produces a compound lever action of `less speed and greaterpower toward the end of the compression. At the same time the ec.centric is in'such position that its larger curvature outside of itsfulcrum-sh'aft 15 will act,

through the chain, rapidly upon the levers and follower, and as thefollower approaches' the bottom and the compression is nearly completethe smaller portion of the eccentric arrives beneath the chain, thusgiving the greatest amount of power. tov compress the bale.

The upper or vertical portion A of the press is preferably hinged to:the stationary base-timbers 16, as shown at 17, so that the press-boxmay be turned down to lie in a hori? zontal position for transportation,and the Adirection-pulleys l0 being journaled in the base-timbers willnot be vmoved or affected by the' turning down or up of the press-box.

The eccentric or power wheel has -tiXed to ita stop 18 in such aposition that when the sweep 19, to which the team or other power isattached, arrives at a certain point during its revolution it causes thestop 1'8 to engage the lever '20, to which the end of the chain 13 isattached, and the further rotation of the eccentric windsthe chainaround said eccentric, and thus -aets through its connections upon thefollower, as previously described. When the compression has beencompleted, the end of the lever 2O rides up on an incline 21, which isin the line .of movement of the lever, and the end of the lever 2() isthus raised suliiciently to disengage it from the IOO.

IOS'

stop 18 and allow the lever to be turned backwardly. This backwardmovement is effected by the engagement of a lug 22, which is carried bythe sweep with a lever 23, the inner end of which is eccentricallypivo'ted to the frameabove with the eccentric'14, as shown at 24. Thisengagement ofthe arm 22 with f the end of the levei 23 acts through achain 25, which is connected with the lever 23, to raise the follower.The chain 25 passes around a direction-pulley 26 at the base of thepress-body. Thence a chain extends upwardly and at a suitable point isdivided into two chains 25lrl which )ass over direction- )ulleys 27, andthe chains 25n pass thence down to the junction of thefollower-actu'atin g levers 4 and 5. so that the pull upon the chainimmediately acts to raise these levers and with them the follower. Asthe lever 20 is now released by reason of the disengagement of saidlever from the stop 18, it will be seen that the eccentric is free toreturn about its pivotpost l5, and thus allow the chain 13 to unwind andthe chains 8 to be extended in unison with the upward movement of thefollower. As the lever 23 is eccentrically attached, as shown at 24, thecontinued movement of the sweep 19 will cause the lug or hook 22 togradually nieve outward beyond the end of the lever 23, so that byreason of the eccentric attachment of the lever 23 this lug 22 will bedisengaged therefrom and leave the lever and its chain connection withthe follower-levers free to move in unison with the movements of thefollower, when the latter is again depressed. VIn this manner thefollower is alternately drawn down by the power communicated through thesweep to the eccentric 14 and is released and again raised to allowanother charge to be placed beneath it.

The incline 21 is pivoted or otherwise made conveniently movable, sothat when the last charge to complete the bale has been placed in thepress this incline may be swung out of line of the lever 20, and thelatter not then beingI raised and disengaged it will be seen that thefollower will be held down by the power applied tothe sweep and canremain in this position until the cords or wires by which the bale issecured have been passed around the bale and tied. Then the lever 20 maybe raised by a hand-bar or otherwise and the parts disengaged. Theincline 21 being swung back to its normal position, the parts will be inreadiness to press another bale.

The successive charges of material which are compressed by the descentof the follower are prevented from again rising by the usual hingedretainers, which consist of bell-crank latches 28, pivoted so that theirpoints project into tlie interior of the press. These latches are freelymovable in one direction to allow the material to pass downwardly, butare Weighted or otherwise arranged to return and project above thematerial as soon as it has passed and to hold it in place while thefollower is again being raised.

In order to discharge a completed bale, a door, as 29, is hinged uponthe side of the press-box opposite the position of the compressed baleand is held in its closed position by means of a swinging bar 30, hingedto the l side of the press and adapted to pass over the outer end of thedoor after it is closed.

In order to free the bale and allow it to be easily removed from thepress-box, l have shown the following arrangement: It is desirable thatthe bale should be rectangular` and for this three sides of thepress-box provide. The other side 31 is beveled or inclined so that thespace is wider next the dooi than toward the opposite side. Across thisspace is a heavy piece of boiler-plate 32, one edge of which is pivotedor loosely held, as at 32', in the side of the press opposite thedoor-opening. The door carries an edge plate, as at 33, contiguous toits hinge 34, and this edge plate passes beneath or behind the plate 32when the door is closed, and this holds the plate 32 substantially atright angles with the sides of the press-box and forms a rectangularchamber for the bale. As soon as the door is opened the removal of theplate 233 from beneath the plate 32 allows the latter to swing and lieagainst the inclined side 3l, so that the pressure upon the bale will berelieved suiiiciently to allow it to be withdrawn from the press.

The material may be supplied to the press by means of a hay-fork andderrick or other device, through the aid of which the material may bedeposited upon a platform 36, conveniently disposed with relation to thedoor 3T, through which the supply is delivered into the press-box. Thisdoor is hinged at the bottom, as at 38, and its upper outer edge is thusallowed to turn in a ipiadrant, so tliatit opens outwardly anddownwardly, and the charge may be delivered into the press through theopening which the door serves to close. Then the charge has been placedin the press, the door is closed by a pull upon the chains 39. Thesechains have one end connected with the door near the inovable edge. Theypass thence around guidepulleys at 40, which aie located iii suchposition with relation to the door that the pull upon the chain will besubstantially at right angles with the movement ol the door. Thus thedoor may be closed against any pressure of the material which iscontained within the press-box. From the pulley 4() a chain leads over apulley 41, journaled on the follower, so that the upward movement oi thefollower will pull the chain and close the door, and its downwardmovement will slacken the chains and release the door.

41L is an attachment for the end of the chain and is movable up or downto insure the proper closing of the door.

43 is a latch or latches fulcruined so as to engage the edge of the doorwhen it is fully closed. These latches are pressed downwardly by springs44, so that they will antomatically engage the door when closed. vIn

i order to open these latches, they have arms projecting from oppositesides of the fulcrumlOO llO

vpoint 45, and to these arms are connected chains 46. The lower ends oflthese chains are connected with levers, as 47, which project intotheline of the'sl'ot or channel 3', in which the follower` end s move, 'sothat as the follower moves downward to compress the charge which iswithin this portion of the press it` engages and pulls upon the leversLL7,thus

tilting the latch and releasing the door 37, which can immediately falloutward'and bc ready for another charge, while the follower continuesits downward motion to complete the compression of the charge.

The plate 33 is securely bolted tothedoor 29 and moves with it, so thatthe opening or closing ofthe door' will move the plate82automaticallyand without other care or attention. i i
